General Description:
Tretinoin is available in 10-mg capsules for oral administrationin the treatment of APL. The mechanism of action involvespassive diffusion through the cell membrane andthen movement to the nucleus where it interacts with theretinoic acid receptor (RAR) portion of the PML-RAR fusionprotein. Binding of tretinoin allows the cell to differentiateand has also been shown to result in the destruction ofthe PML-RAR fusion protein. Resistance to tretinoin isproblematic and associated with an increase in cellularretinoic acidinding proteins (CRAPBs) located in the cytosol.The complexation with tretinoin prevents movementinto the nucleus and may present the drug to metabolizingenzymes that inactivate it. Amino acid mutation of thePML-RAR protein has also been established as a mechanismof resistance. The agent is well absorbed upon oral administrationand highly (95%) protein bound. Metabolismoccurs in the liver and several inactive metabolites havebeen identified including 13-cis-retinoic acid, 4-oxo cisretinoic,4-oxo trans-retinoic acid and 4-oxo trans-retinoicacid glucuronide. Elimination occurs in the urine (63%) andfeces (31%) with an elimination half-life of 40 to 120 minutes.Vitamin A toxicity is seen in nearly all patients andpresents as headache, fever, dryness of the skin, skin rash,mucositis, and peripheral edema. APL differentiation syndromesuch as that seen for trioxide also occurs.Cardiovascular effects include flushing, hypotension, CHF,stroke, and myocardial infarction have been reported butoccur only rarely. There are also several CNS and GI effectsthat have been associated with the agent as well.
Uses:
(1) Applies to abnormal tyshiyongyupe of acne, fish phosphorus disease and abnormal psoriasis.
(2) Resistance to abnormal skin drugs.
(3) Tretinoin mainly affects the growth of bones and epithelial metabolism, can promote epithelial cell proliferation and updates, and can inhibit the proliferation and differentiation of keratinocytes, so hyperkeratosis can be back to normal. Therefore many complete or incomplete keratosis, hyperkeratosis of diseases have a certain therapeutic effect, treat a variety of skin diseases. Tretinoin is mainly used in the treatment of psoriasis, ichthyosis, follicular keratosis, acne, lichen planus, verrucous epidermal nevus, impetigo, vitiligo, lichen psoriasis, the face of pityriasis alba, etc.
